FIELD: blasting operations.
SUBSTANCE: invention relates to explosion-proof devices and can be used for explosion protection of process equipment. Explosion-proof device with a bursting disk, containing a body, a bursting disk element, a lined cargo gate, the valve body is made in the form of a lower cylindrical, middle conical and upper cylindrical parts, in the lower cylindrical part a lined cargo gate is placed, in the upper cylindrical part of the valve body there is a mounting unit for a bursting disk element, the movable connection of the lined cargo gate with the body of the object to be protected is made in the form of guide rods, the middle part of which is movably placed in the sleeves, and the lower end of each of them is connected to the body by means of a flange, at the other end of the rods the stop plates are fixed, on which the explosion-proof elements are fixed, there are fast-disintegrating under the action of the primary impulse of the blast wave elements between explosive elements and a lined cargo gate, made in the form of bushings covering the guide rods.
EFFECT: increase the efficiency and reliability of protection of technological equipment from explosions.
